Hydroponic is a method of growing plants without soil, using nutrient-rich water instead. This technique allows plants to absorb essential nutrients directly through their roots, promoting faster growth and higher yields. Hydroponics can be used for various crops, including vegetables, herbs, and fruits. There are several systems of hydroponics, such as deep water culture, nutrient film technique, and aeroponics. Each system has its own way of delivering nutrients and oxygen to the plants. Hydroponics is often used in controlled environments like greenhouses, making it possible to grow food year-round, regardless of outdoor conditions.
